Arrange the canned, drained chickpeas on a baking sheet lined with parchment paper.
Pop in the oven preheated at 350°F and bake for about 15 minutes or until they have slightly dried out.
Remove and let them cool down, then add them to a food processor jar.
Blitz until you get coarse crumbs.
Transfer the crumbs back to a lined baking sheet.
Spray some oil over the crumbs and season with salt, pepper and garlic powder. Bake at 350°F for another 15 minutes or until almost all of the moisture is gone and the crumbs are dry.
Notes
Drain and pat the canned chickpeas thoroughly dry before baking to help remove excess moisture.
Spread the chickpeas in a single layer on the baking sheet so they dry evenly during the first bake.
Let the chickpeas cool slightly before transferring them to the food processor.
Pulse in short bursts until the chickpeas resemble coarse breadcrumbs. Avoid overprocessing, as they can turn into a paste.
Spread the crumbs in a thin, even layer before the second bake to help them crisp up uniformly.
Adjust the garlic powder, salt, and pepper to taste, or add smoked paprika, Italian seasoning, or chili flakes for extra flavor.
Let the crumbs cool completely on the baking sheet before storing, as they will become crispier as they cool.
Sprinkle over soups, salads, roasted vegetables, or pasta dishes, or use as a crunchy alternative to breadcrumbs.
Store cooled crumbs in an airtight container in the refrigerator, or freeze for longer storage. Reheat briefly in the oven if they lose their crunch.
